Adafruit ST7735 library: 'sendCommand' was not declared in this scope

Hi,

i'm just trying to use the plain Adafruit ST7735 library. I installed it via the library manager but as soon as I even try to compile one of the included example projects I get bombarded with compiling errors regarding the sendCommand function.

C:\Users\Paul\Documents\Arduino\libraries\Adafruit_ST7735_and_ST7789_Library\Adafruit_ST7735.cpp: In member function 'void Adafruit_ST7735::initR(uint8_t)':

C:\Users\Paul\Documents\Arduino\libraries\Adafruit_ST7735_and_ST7789_Library\Adafruit_ST7735.cpp:242:40: error: 'sendCommand' was not declared in this scope

     sendCommand(ST77XX_MADCTL, &data, 1);

As I don't think that the library is overall faulty I assume that I did something wrong or overlooked something. Can anyone tell my what exactly?

Best regards, Paul

You must always install / Upgrade the Adafruit_GFX library (via the Library Manager)
